You can't use the automatic EDV compensation if you can't program the CEDV coefficients. Do you have the coefficients from GAUGEPARCAL? If so, you can use your host uC to program the coefficients via I2C. See 6.1 Data Memory Parameter Update Example,…

Hello Tom
For very low temperature operation, there is additional information required. There are online tools to help tweak the chemistry data.
Please see GAUGEPARCAL and GPCRB tools for more information
Michael,
The gauge will constantly be learning. The 6 cycles can be done outside of the system and just collected on the bench. They are used to establish the "EDV" end voltage points. The procedure to follow is located here https://www.ti.com…
Grandaphi,
Currently this cell does not exist in our database. I was waiting to reply hoping someone from the community could have a better answer. I do suspect you will find a match to an already existing chemID.
As i assume you are doing please use…

Widji,
When using a new battery the best thing to do it to run a match using our GPC online tool https://www.ti.com/tool/GAUGEPARCAL . If the ID you used is in the list the you should be ok to proceed with the learning.
The sysrate log file you provided…
